MACHINE F03 MARKING LINEIRT AND THE LIKE,

Application filed January 22, 191-5.

To all whom it may concern Be it known that we, ARTHUR HAMMER, a subjectof the Emperor of Germany, and residing at Berlin, Germany, and FnrrzEcnnsoonrnn, a subject of the Emperor of Germany, and residing atBerlin-Charlottenburg, Germany, have invented certain new and usefulImprovements in hlachines for Marking Linen and the like, of which thefollowing is a specification.

Our invention relates to a device particularly intended for laundriesand has for its object, a machine for mechanically marking andattaching, in a simple and rapid manner the appendages or tags whichvconsist usually of a piece of tape, bearing suitable identificationcharacters, for the purpose of identifying the articles to be washed.

According to our invention the marking, cutting off and stitching on ofthe tags serving for identification of the articles is carried out inone operation by a simple actuating of a pedal or the like, so that anoperator is able to provide several thousand articles with tags in anhour without difiiculty.

The new machine consists substantially in the combination of a stampingdevice, a cutting off device and a sewing machine, which, with the helpof a feeding device for the tape, coact in such manner, that at eachoperation of the driving mechanism. a part of the tape is stamped,another part is cut off and stitched on, whereupon the feeding forwardof the tape is effected by the feeding device which is also controlledby the driving mechanism.

In the drawing our invention is shown by way of example in one form ofconstruction as follows Figure 1 shows the new machine at rest in frontelevation,

Fig. 2 shows it in plan at the end of the stroke of the operating lever,while Figs. 3 to 6 inclusive illustrate details.

The device consists substantially of the stamping device 2, the sewingdevice 8, the cutting off device 4: and the feeding device 5 which arearranged on a common base-plate l to be fixed to a table or the like.

lhe driving of the various organs is effected by means of a pedal, notshown in the drawings, which is connected by means Specification of.Letters l atcnt.

of a rod 6 with a lever 8 mounted at 7 at the rear part of the frame ofthe stamping device. The lever 8 is drawn upwardly by a coil spring 9.the upper end of which is attached to a lug 10 of the frame of thestamping device 2. The oscillating shaft 11, on the back end of whichthe lever 8 is mounted, rests at its forward end in a bearing 12corresponding to the bearing 7, and which, like the latter, is providedon the frame of the stamping device. Between the two bearings. theoscillating shaft 11 carries a second lever 13, the free end of which.is provided with a toothed segment 14 which meshes with a pinion 16which is rigidly connected to cam 17 which is mounted loosely on theshaft of the sewing machine 3 and which serves for driving the stampingdevice as well as the cutting off device.

The drive for the stamping device is transmitted by means of a lever 18,which is mounted on an oscillating shaft 19, which rests in bearingsprovided on the frame of the stamping device 2, of which only the frontbearing is shown in Fig. 1, while in Fig. 2 both bearings as well as aportion of the shaft 19 are omitted. in order to show better the partsof the machine lying below same. On the shaft 19 there is mounted a coilspring 19 which acts on the said shaft 19 in such a manner that thelever 18 has its sliding roller pressed against the circumferentialsurface of the cam 17. Q11 the front end of the shaft 19 there ismounted a lever 21, the free end of which, provided with an antifrictionroller 2 extends through a slot 23 into the casing 25 which carries theplunger 24: of the stamping device, and engages in an aperture 26 of thestamping plunger. The lower end of the plunger 24 is provided with aforkshaped headpiece 27 between the prongs of which the actual stamp 28is supported. The stamp consists of, a series of type-disks, which areconnected with corresponding disks 29 situated on the exterior of thefork head 27 in such a manner that by turning the disks 29, thetype-disks can be adjusted as desired from the outside.

The cam 17 is provided on the front with a protuberance 30, with whichthe sliding roller 31 of a double-armed lever 33 mounted at 32 on theframe of the sewing device 3 coacts, the other end of said double-armedlever 33 forming the knife 34 of the cutting off device 1. The cuttingedge of the knife coacts with a cutting edge 35 of the baseplate 1,which is formed by an opening 36 in the base-plate 1. To the right ofthis opening is situated the point at which the piece of tape 37 cut offby the cutting device is stitched to the article to be washed, while tothe left of the edge 35, the tape to be cut is clamped securely by aclamping device 38. The clamping device is guided in a lug 39 of theframe of the stamping device and is provided with a resilient pin 40,which lies within the range of action of a curved member 4:1. which isarranged laterally on the knife 34:, in such a manner that when theknife 34 carries out its cutting action in the manner described below,the member 41 presses on the pin 10 and thus forces the shoe 38resiliently against the tape lying on the base-plate, in order tofacilitate the cutting operation.

The conveying of the tape 37, which is wound off a supply drum 42 andwhich passes over a guiding roller 43 arranged on the left-hand side ofthe table, is'effected by means of two feeding rollers 4e1- and 4:5arranged vertically one above the other.

On the shaft 63 of the lower roller 45 a toothed pinion 51 is looselymounted, which engages with a rack 4-8 guided in two lugs d6 and 47 ofthe frame of the stamping device and drawn upward by a coil spring 1-9which is fixed to the lug e6, the upper end of said rack engaging with aspur-wheel 50 mounted on the oscillating shaft 11. The toothed pinion 51has coupling teeth 61 proje'cting from its rear end face and engagingwith opposing coupling teeth of a lock ing-wheel 59 shiftably connectedto the shaft 63 and pressed against the pinion 51 by means of a spring64L coiled around the shaft 63 and bearing against a collar 65. A pawl62 mounted on the machine frame onthe locking-wheel. From the drawingthere may be easily seen that in a downward movement of the rod 6, whichcauses also a downward movement of the rack by the intermediary of shaft11 and spurwheel 50,the pinion 51 will be rotated in the directioninverse to the arrow. But it will turn freely on the shaft 63 and itscoupling teeth slide over the coupling teeth of the locking-wheel 59which is prevented from rotating by the pawl 62, but will reciprocatelengthwise under the combined in-,

fiuence of the coupling teeth and spring 6 1. W hen however the red 6moves upward and therefore the pinion 51 is rotated in the direction ofthe arrow, the locking-wheel 59 will be carried along by means of thecoupling teeth 61, 60 and will rotate the shaft 63, so that the rollers15, 4:4, receive their feeding movement.

The sewing device 3 is a so called zig-zag stitching machine which makeszig-zag stitches in known manner as shown in Fig. 2 in dotted lines. Thezig-zag stitching machine stitches the piece of tape which has beenmarked by the stamping device and cut off by the cutting device on tothe article to be washed with a few wide stitches. The sewing machine isoperated at intervals only. For this purpose its driving gear is madedependent on the pedal rod 6 through the intermediary of lever 8,toothed segment 1 1 and pinion 16. The latter is, as already mentioned,mounted loosely on the shaft 15, which carries at its forward end thegear (not shown in the drawing) for driving the needle-rod 52 and thepresserfoot 53. The cam 17, which is integral with the pinion 15, isfitted with coupling teeth 5% on its front face which teeth correspondto coupling teeth on the rear face of a locking-wheel 56 fixed on theshaft 15 and coacting with a pawl 57. The pinion16 is influenced by acoil spring 55 arranged on the shaft 15. When the rod 6 movesdownwardly, the pinion 16, which is rotated in the direction of thearrow, shown in Fig. 1, carries with it the shaft 15 by the intermediaryof the coupling teeth 5%, while when movement is made in the oppositedirection, the coupling teeth, 54 of the cam 17 slide over thecorresponding coupling teeth of a locking-wheel 56 without rotating thislocking wheel and the shaft 15 along with them which is obtained by thecam 17 being axially movable against the action of the spring 55 and thelocking-wheel 56 being engaged by the pawl 57.

The gear ratio between the toothed segment let and the pinion 16 is sochosen, that the stitching machine effects only a few stitches at eachoperation of the actuating pedal, which suiiice for attaching the pieceof tape to the article to be washed.

The mode of action of the machine is as follows:

The article which is to be marked, is placed with its part on which thedistinguishing appendage is to be attached on the table of the sewingdevice 3, beneath the stamped end of the tape 37 fed upon said table inthe preceding operation of the machine. If the pedal is actuated, theshaft 11 describes a corresponding oscillation which, by means of thetoothed segment 14, the cam 17 and the levers 18 and 21 causes a sinkingof the stamp 28, whereby the particular number required is printed onthe tape portion lying beneath the stamp 28. At the same time thestitching machine, the shaft of which makes a few revolutions by meansof the toothed segment 14;, the pinion 16 and the coupling 54- sews thecut off end of the tape which is lying on the article to be washed, onthe said article. Simultaneously the rack 48, moved downward by means ofthe pinion 50, rotates the pinion 51 freely on the shaft 63 as abovedescribed, so that the rollers 45, 4% remain at rest. To ward the end ofthe stamping and sewing operation the knife 34c is moved in a hackwarddirection by means of the projecting piece 30 situated on the cam 17 andthe lever which is subjected to the action of the spring 58 (Fig. 3),whereby the member presses the clamp 38 on to the tape which is cut elfby the knife. in releasing the pedal, the whole of th elements return totheir original position under the influence of the spring 9 acting onthe lever 8, with the exception of the locking-wheel 56 which is mountedrigidly on the shaft 15 of the sewing machine, said locking-wheelremaining in its position and bein rotated'iurther at the nextoperation. Simultan ously the pinion 51 carries along with it the shaft63 and roller L5 in the direction of the a row, so that the free end ofthe tape is fed forward pen the table of the sewing device, past thecutting edge 35 and the rising knite ea, for being attached to anarticie during the following operation of the machine.

The invention is no restricted to the particular kinds of individualdevices as dcscrihed. For example, the zigzag stitching machine could bereplaced by an ordinary sewing machine.
